Pathology 9 - MSK Flashcards
RC tear - cause of tear
traumatic
or
degentrative
RC tear - special tests
drop arm
painful arm
ER lag sign
RC - MMT’s
RC tear - degentractive tear population
> 50
due to chronic degen patho
RC tear - partial thickness tear vs full thickness
partial : only through part of the tendon
full: complete tear of the tendon
RC tear - size of full tear
1 cm = small
5 cm = large
RC tear - signs and symptoms (arm position)
add and IR
RC tear - signs and symptoms
point tenderness at greater tubercle and acromion
lack of shoulder flexion and abd - upper trap recruitment
increased tone in anterior shoulder region
pain in lateral shoulder and raditing pain in the upper arm
RC tear - how long is immoblization normally after surgery for large tears
4-6 weeks
RC tear - how long to return to function actives that include over head actives
9 - 12 months
RC tear - what tendon is often involved
supraspinatus
with more traumatic subscapularis and infraspinauts may get involved
RC tear - what is the most common complaint
pain and weakness
what nerve serve the subscapular muscle
subscapular nerve (C5,6,7)
what does the suprascapular nerve serve in the RC
infraspinatus and supraspinatus
C5 and C6
what nerve serve the teres minor
axillary nerve
C5 and C6
what is the function of the suprspinatus
assist with abd
depress the humeral head
what is the function of the teres minor and infraspinatus
ER
GH ext - just infra
what is the function of the subscapularis
IR
depress the humeral head
RC - is pain normally more with full or partial tear
patrial tear because of the pressure on the remain tendon
RC tear - imaging
MRI
special tests for the supraspinatus
empty can
what is more aggressive ampty can or full can
empty can
this why we test it second
biceps tendon rupture - pop
men 40-60
secondary to chronic inflammation or degeneration
biceps tendon rupture - pain presentation
worse with overhead activities
pain is the primary characteristix
what are the special tests for a SLAP lesion
Obrien’s
anterior slide test
biceps 1 and 2
crank
what are the special test with SLAP lesion and long head of the biceps tendon
YSL
yergasons
speeds
will osgood-schlatter diease take care of it self
yes the condition normally resolve in time without intervention
Osteogenesis Imperfecta - what kind of disorder
congenital connective tissue disorder
